Dev finds backend architecture only proves its worth when wired to real user flows

A developer building a TypeScript-based Candidate Tracker completed over 100 tests and set up multiple backend layers—including Prisma, PostgreSQL, and validation services—before any usable interface existed. Progress felt stalled until a full Company management workflow was connected end-to-end through Next.js, covering everything from browser form input to database persistence. Once real user actions crossed every architectural layer, previously abstract design decisions became tangible and justified. The experience highlighted that Server Actions function as genuine public input boundaries and that browser-side validation alone cannot secure the server. The key takeaway was that architecture requires a real consumer—a working user workflow—before its value and trade-offs become clear.
